Read ?plot.lda, which tells you the ... arguments are (for dimen=1, the
only option for two groups) passed to ldahist, so then read its help page.
I don't know what you want (and your example is not reproducible): I would
expect you to get a single plot with two panels (figures), but there are
options to have a single panel. (Reading 'An Introduction to R' may help
you to use standard terminology that others will be able to follow.)

But the version of MASS is what is relevant, and it would have been in
the sessionInfo() output the R posting guide asked you for.
